"When winter rolls around, many landscapes go through dramatic changes that open up new possibilities for great photos. Snow-laden trees, icicles, frost patterns on foliage and winter sports are just a few of the many options. While many cameras are designed to work flawlessly at even down to 32 °F (0 °C), most will operate beyond this with a few simple precautions.
If you take a camera into a cold environment, the first thing you might notice is that battery life begins to drop. By 32 °F (0 °C), you might only lose 10% of the battery’s potential, but if it grows colder then it starts to become more noticeable. The first step to combat this is to keep your spare batteries inside your clothing, as close to your body as possible. In moderately cold conditions, this will be more than enough to keep the batteries within a normal operating range. It might be tempting to keep smaller point-and-shoot cameras inside your layers as well, but even in cold temperatures, we sweat when exerting energy like when you’re walking through deep snow or skiing. This sweating will cause condensation on your lens and potentially inside your camera, so it’s best to keep smaller cameras in a backpack or outer pocket."

Using DSLR Controller + TP-LINK Portable WiFi Router
Admittedly, I had some trouble getting DSLR Controller to connect with my Google Nexus 7 (original version) using the TP-Link Portable WiFi Router. However, once connected, everything worked quite well. The refresh rate on my Nexus 7 was very good; Live View video was very smooth. Exposure controls, camera settings and focus were relatively easy to manipulate using DSLR Controller. Being able to see the camera's Live View video made framing the self-portrait incredibly easy (and fun).
The DSLR Controller app + Portable WiFi Router combination can be used for so much more than making self-portraits easier. Some of my favorite features include HDR capture, timelapse, and focus stacking.
Speaking of focus stacking, I used DSLR Controller with the Portable WiFi Router hooked up to my EOS 7D and EF 100mm f/2.8 macro lens (set to f/8) to create the image of the almond seen below. The final image was created by stacking 38 incrementally focused images with CombineZP (free focus-stacking software).
DSLR Controller even has a "Strobe Recharge Delay" setting that enables you to specify a time delay between shots so that any flashes you're using have time to recharge. For the shot above, a strobe delay setting of 3 seconds allowed my PocketWizard PlusX-triggered 580EX with LumiQuest Softbox LTp to recharge and prevent overheating.
I had absolutely no issues getting DSLR Controller to connect with my "wireless" EOS 7D. The setup worked flawlessly. After easily and reliably being able to connect the setup with my 7D, I tried trouble shooting the setup with my 5D Mark III. I finally figured out that TP-Link Portable WiFi Router simply takes a while to estabilish a connection with the camera (more than 60 seconds). DSLR Controller has some tips for troubleshooting issues on their FAQs, so you may want to read over those if you have trouble getting DSLR Controller to connect.
Update: Regarding the 5D III specifically, I've noticed that DSLR Controller will not want to connect if you are recording images to one card and playing them back using the secondary memory card. Be sure that your "Record func+card/folder sel." setting has "Playback" set to Card 1.
I've also had more success with these steps as opposed to the ones listed on DSLR Controller's website (again, specifically regarding the 5D III). If the connection steps on DSLR Conroller's website don't work for you, try this:
Although I was using an original Google Nexus 7 tablet, DSLR Controller notes that some people have experienced issues with the newer Nexus 7 FHD tablet released in 2013. If you're wanting to purchase a tablet specifically for DSLR Controller use, I'd stick with the original Google Nexus 7 or another device listed as compatible with DSLR Controller.
Despite the connection issues with my 5D III, I'm really happy and excited about this setup. Once everything gets connected the setup works beautifully. I've been having tons of fun with it and I've barely scratched the surface of what DSLR Controller can do. If you already own a compatible Android phone or tablet, then the DSLR Controller App ($7.99) and TP-LINK TL-MR3040 3G/4G Wireless N150 Portable Router ($34.99) combination can be more fun and creatively inspiring than the [small] financial investement would suggest.
Note: Jorrit Jongma, the developer of DSLR Controller, reached out to me and requested I mention a couple of things. The custom firmware loaded on the TP-Link portable router is OpenWRT firmware which should offer many of the same features (and more) of the original firmware (although converting the device back to the original firmware can be tricky). Also, if your camera features built-in Wi-Fi (like the EOS 6D and 70D), DSLR Controller will work directly with your camera (and offers more functionality than Canon's OEM WiFi app).
